The movie, from The Queen director Stephen Frears, follows Armstrong's career from his cancer battle to the scandal that ultimately brought him down. After years of denying that he used performance-enhancing substances, the seven-time Tour de France champ admitted to Oprah Winfrey in January that he had injected testosterone and took part in blood-doping. The interview came after he was stripped of all seven Tour de France titles, as well as his Olympic gold medal.
